Hi hear4u, welcome to the forum, I am so pleased you found us.
It is scarey being on your own, isolating away from those around you. It is also so easy to isolate, and the longer we isolate the harder it is to break out of the cycle. Along with all the other PTSD symptoms it is a very bumpy rollercoaster ride.
You have made a great start by reaching out to us and introducing yourself. Reward yourself for doing that. There is some great articles and member threads so have a look around. For me it was a huge relief that finally I was somewhere where people understood, I would read a thread and think I could have written that.
You may be isolating and on your own but you are no longer alone.
I'm often in chat, so if you feel like it drop in and see who is around.
Take care
KP
